How to choose a water treatment company in Prescott

This page does not rank companies. A list that happens to end with the author is not a list.

Verify the license

Arizona keeps a public register of every licensed contractor. It takes two minutes.

1. Open the Arizona Registrar of Contractors' Contractor Search. The tool itself sits at azroc.my.site.com/AZRoc/s/contractor-search.
2. Search the ROC number from their truck, card or website. If they will not give you a number, that is the answer.
3. Confirm the license is active, the classification covers plumbing or water treatment, and the business name matches the name on your estimate.
4. Read the complaint history.
5. Then the step most people skip. ROC advises you “verify the person you are negotiating your project with is an authorized representative of the licensed contractor by calling the contractor's number listed on the ROC license record.” Call the number on the register, not the number on the card.

The Registrar also answers on (602) 542-1525 or 877-692-9762. The consequence of skipping all this, in ROC's words: “you as the property owner have no recourse through AZ ROC if you hire an unlicensed entity.”

One honest wrinkle: not all plumbing work requires a license. Under A.R.S. § 32-1121(A)(14), a job under $1,000 total that needs no permit and involves no gas may be done unlicensed, provided the person says “not a licensed contractor” in their advertising. That is legal. It also means the protections below do not apply to it. A whole-house treatment system is far over the threshold, so it is licensed work either way.

Bond, Recovery Fund, insurance — three different things

The bond is a licensing condition. ROC sets it at $9,000 for residential contractors under $750,000 annual volume and $15,000 above. Anyone harmed can claim against it, but ROC's FAQ notes the limit: “It is possible that a contractor's bond could be depleted before you make recovery.” It is a shared pot, not a policy on your house.

The Residential Recovery Fund is separate, funded by licensed residential contractors, and pays “up to $30,000 to have the work corrected or completed,” capped at $200,000 per license across all claimants, with claims filed within two years of occupancy or last work.

Insurance is neither. General liability covers damage they do to your property; workers' compensation covers their people. Those are the ones that matter when a fitting lets go at three in the morning.

A flag worth stating: we could not find a statement on ROC's published pages confirming whether Arizona requires licensed contractors to carry general liability or workers' compensation as a condition of licensure. Do not assume either way. Ask for a current certificate naming the company on your contract, and ring the insurer.

What a fair price looks like

There is no fair price in the abstract, because the equipment should be determined by the water. A quote produced before a laboratory result is a quote for something the company already meant to sell.

• What number is this sized to? A softener is sized to hardness and household demand; an arsenic system to an arsenic concentration and a pH. No input numbers, no defensible output.
• Where did that number come from? A certified laboratory, or a meter at your sink.
• What does it cost to run? Salt, cartridges, membranes, service intervals. Ten years of consumables often exceeds the install.
• Certified to what standard, for what contaminant?

ROC's baseline holds: “ask for written estimates from at least three (3) contractors,” each with “a detailed list/description of the project, including the price, the responsibility to obtain building permits.” Three quotes against one lab report is the only real price comparison available to you.

Verify the equipment, not just the company

NSF/ANSI standards are how a manufacturer's claim gets independently tested. 44 covers cation exchange softeners. 58 covers reverse osmosis. 53 covers filters certified to reduce a contaminant “with a health effect.” 42 covers aesthetic reduction only — chlorine, taste, odor, nothing health-related.

Ask which standard the specific model carries and for which contaminant, then check it in NSF's certified products listing. “NSF certified” with no standard number and no contaminant named is marketing. A 42-certified filter sold as arsenic protection is still a 42-certified filter.

For people rather than products, the Water Quality Association runs voluntary certifications — Certified Water Specialist, Certified Installer, Master Water Specialist — with a public directory. Not a license, not a substitute for one, but it means somebody sat an exam.

The tactics to walk away from

The free in-home test that condemns your water

A handheld meter measures hardness, chlorine, total dissolved solids and pH. It cannot measure arsenic, bacteria, nitrate, lead or uranium — not poorly, at all. Arizona's own drinking water field method rules approve field testing only for chlorine species, chlorite and turbidity, and require everything else be “conducted by laboratories that have been certified by EPA or the Arizona Department of Health Services.”

So a meter reading followed by the word “unsafe” is a sentence with nothing behind it. Same for the demonstrations: the electrolysis jar that turns brown, the precipitate test, the soap-lather comparison. Those are chemistry demonstrations of dissolved minerals, not analyzes, and they produce no number you can act on.

Pricing that expires today

A system correctly sized to your water is still correctly sized next Tuesday. A discount that dies at the end of the visit exists to stop you getting the other two quotes.

Money moving before work does

ROC: “never pay in cash,” “make checks payable to the name of the company/contractor listed in your signed contract,” and “do not allow payments to get ahead of the work.” ROC also advises avoiding “door-to-door solicitors offering low cost construction services.”

A whole-house system for a drinking-water problem

Not dishonest, often oversold. On arsenic, Arizona Cooperative Extension's AZ1650 notes “point-of-use treatment can often treat enough water needed for drinking and cooking, while keeping installation and maintenance costs lower.” The washing machine does not need arsenic-free water.

Then retest, somewhere else

AZ1650 is firm: “test your treated well water for arsenic every year using a state-certified laboratory.” In its own study of five Arizona homes, one reverse osmosis system removed 85 percent of the arsenic and the treated water was still above the limit. Get the retest from a laboratory, not from the company that sold you the system.

Where this site fits

For completeness, since you are reading this on a plumbing company's website: the business behind this page is not a licensed contractor, works under the handyman exemption described above, and is not booking new work at present while Arizona contractor licensing is in progress. Apply every check above to CreekWell exactly as you would to anyone else.

Common questions

How do I check if a water treatment company in Arizona is licensed?

Use the Arizona Registrar of Contractors' Contractor Search at roc.az.gov/contractor-search. Search the company's ROC license number and confirm the license is active, the classification covers the work, and the business name matches your estimate. Then call the phone number listed on the ROC record itself to confirm the salesperson is an authorized representative. ROC states that if you hire an unlicensed entity you have no recourse through them.

Is a free in-home water test worth anything?

It is worth four numbers: hardness, chlorine, total dissolved solids and pH. A handheld meter cannot detect arsenic, bacteria, nitrate, lead or uranium. Arizona's drinking water rules approve field methods only for chlorine species, chlorite and turbidity, and require all other analyzes to be performed by laboratories certified by EPA or the Arizona Department of Health Services. A free test is a legitimate sizing tool. It is not a safety assessment.

What is the difference between a contractor's bond and insurance?

A bond is a licensing condition, set at $9,000 or $15,000 for Arizona residential contractors, that harmed parties can claim against, and the Registrar notes it can be depleted before you recover. The separate Residential Recovery Fund pays up to $30,000 per residence for work by licensed residential contractors. Insurance is different again: general liability covers damage to your property and workers' compensation covers injuries to their workers. Ask for a current certificate of insurance and confirm it directly with the insurer.
